Air massage device

Abstract

Provide is an air massage device including a plurality of air bags; an air pump 31 for supplying air into each of the air bags; solenoid valves 32 for switching on-off of air supply into each of the air bags; and a control part for changing an electric input value into the air pump 31 and an amount of the supplied air into each of the air bags per unit time to open and close each of the solenoid valves 32 so as to correspond to this change of the amount of the supplied air.

What is claimed is: 
     
       1. An air massage chair device, comprising:
 a plurality of air bags, wherein each airbag comprises a plurality of airbag carriers overlapped and integrally connected with one another forming one internal air room communication; 
 an air pump for supplying air into each airbag of the plurality of air bags; 
 a plurality of air supply valves for switching on-off of air supply into each of the air bags; 
 a storage part for storing an electric input value sent to the air pump and an opening and closing timing for each of the air supply valves; and 
 a control part for controlling an amount of the supplied air into each of the airbags per unit time according to the electric input value, and for repeatedly opening and closing the air supply valves which correspond to the each of the airbags at the opening and closing timing stored in the storage part, and opening and closing of each of the air supply valves depends on the amount of the supplied air into each of the air bags; 
 wherein at a first predetermined electric input value of the air pump, the air pump is configured to provide a maximum amount of air supply into each of the airbags and at a second predetermined electric input value of the air pump, the air pump is configured to provide less amount of air supply than said maximum amount of air supply, wherein said first predetermined electric input value of the air pump is greater than said second predetermined electric input value of the air pump; 
 wherein at a first step of expansion, said each of the airbags are expanded to a first predetermined level with said maximum amount of air supply at a first expansion rate, and at a second step of expansion, said each of the airbags are expanded to a second predetermined level with said less amount of air supply than said maximum amount of air supply at a second expansion rate; 
 wherein said second expansion rate is slower than said first expansion rate; 
 wherein the control part enables the electric input value to be set and each of the air supply valves to be opened and closed based on a plurality of predetermined treatment courses; 
 wherein during treatment operations in one treatment course among the plurality of predetermined treatment courses, the control part, in a first stage, opens the air supply valve corresponding to at least one airbag of the plurality of air bags and sets the electric input value to a high electric value until the at least one air bag is expanded to a certain expanding condition, and the control part, in a second stage, changes the electric input value from the high electrical input value to a low electric input level and repeatedly opens and closes the air supply valves at the opening and closing timing stored in the storage part. 
 
     
     
       2. The air massage chair device according to  claim 1 , wherein the first stage and the second stage of the treatment operations are alternately repeated for at least one airbag on a right side and at least one airbag on a left side of a human body to be treated. 
     
     
       3. The air massage chair device according to  claim 1 , wherein the air supply valves corresponding to the plurality of air bags are opened in the first stage, an air supply valve corresponding to a first pair of air bags of the plurality of air bags is opened after the time when a second pair of air bags of the plurality of air bags has been expanded to a certain expanding condition. 
     
     
       4. The air massage chair device according to  claim 1 , wherein said air massage chair device further comprising a backrest part, two airbags of the plurality of air bags are arranged to be overlapped with each other between a human body to be treated and the backrest part of the air massage chair device;
 wherein the control part opens an air supply valve of the plurality of air supply valves corresponding to an air bag of the two air bags in the first stage, and the control part repeatedly opens and closes an air supply valve of the plurality of air valves corresponding to a second air bag of the two air bags on a side of the backrest part of the air massage chair device in the second stage. 
 
     
     
       5. The air massage chair device according to  claim 1 , wherein the control part enables the air massage chair device to perform treatment operations due to one treatment course in which the electric input value into the air pump is set to the high electrical input level in addition to treatment operations due to a second treatment course in which the electric input value is set to the low electrical input value to elongate an air supply time duration.
